One conjecture I read was the name was chosen so sales could say "your users can query the database in ENGLISH".
Or a language with meta characters in it, such as C++?
Obviously, these two languages are popular now so they are the first hit but you can bet in the early days of the web, it was a bit different.
I understand your point, though, whenever I create a project, I do my best to pick a unique name for that very reason, but overall, history tends to indicate that such decision will not prevent a good product from becoming popular.
1. Because Google already knows that you're a hacker (based on your search history and other info it has on you).
2. Because those are old and famous in their respective communities (ergo page rank and visibility).
3. Because there is actually content for them out there (so it actually has something to present).
It is, incidentally, a pretty neat programming language. It seems like it had a big influence on Python.
Hint: Not Apple's.
